Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to a unified control system for grid-connected power generation and power quality. Background technique [0002] With the continuous consumption of energy, the use of renewable energy is more fully. Renewable energy includes solar energy, water energy, wind energy, biomass energy, wave energy, tidal energy, ocean temperature difference energy, geothermal energy, etc. Nature can be recycled, inexhaustible and inexhaustible. It is a clean, green and low-carbon energy. The total installed capacity of wind power and solar power has reached more than 1.2 billion kilowatts, which further points out the strategic direction of China's energy transformation and reform. China's renewable energy development has set a new navigation mark. [0003] In order to improve the full utilization of energy and the stability of equipment operation during the operation of solar p...

Problems solved by technology

[0003] In order to improve the full utilization of energy and the stability of equipment operation during the operation of solar power generation equipment, it is necessary to cut off the grid-connected power generation circuit according to the needs of use at night and during the day, resulting in frequent cut-offs that will easily accelerate the damage of electrical equipment and reduce Service life of electrical equipment

[0004] In the existing technology, the existing grid-connected power generation system only uses a single solar energy to generate electricity, so that the continuity of electric energy storage is easily interrupted by sunlight. When the solar photovoltaic equipment is laid, the structure of the top plane is not Any shading is more likely to generate a large amount of wind resources. How to make full use of the combination of wind resources and light energy to achieve sustainable power storage remains to be developed and created
